[Bug 1889041] Re: bionic daily install to sdc, reboot and UUID not found (grub rescue)

[Chris Guiver]

An earlier Lubuntu (daily) install was made to SDA without issues.

After the Xubuntu failure... I re-ran Lubuntu install but this time
tried installing to SDC.  It completed and looked good, (just as Xubuntu
did), then on reboot - it dropped to GRUB RESCUE just as Xubuntu did.

I booted the LIVE daily image again, the UUID (now changed due to
Lubuntu re-format of SDC) was the correct one it was looking for ... but
same identical issue.

This box is STRANGE, it has settings for PATA drives, plus SATA, and I
suspect issues is this, ie. a quirk to his box & how it handles PATA &
SATA drives..  MBR security however is & was off.

SDA is PATA  (so is DVD-RW)
SDB & SDC are SATA

Title:
  bionic daily install to sdc, reboot and UUID not found (grub rescue)

Status in ubiquity package in Ubuntu:
  Incomplete

Bug description:
  xubuntu daily (bionic) qa-test install to SDC (full disk)
  on reboot though, system reports UUID isn't found & only grub rescue

  `blkid` reveals
  /dev/sdc1: UUID="72d29572-9844-448c-adda-597d97d1a598" TYPE="ext4" PARTUUID="ec71cd4e-01"
  which is where I installed to, and what it reported (I believe) wasn't found

  please ignore this report until I do more digging, this box isn't used
  except for qa-testing, and I want to ensure I didn't make a mistake.

  (successful test earlier today was to SDA not SDC)

  this system has been rebooted into daily/live for ubuntu-bug, which
  will give me more details to explore I hope.  No ubiquity log as I
  didn't expect issues on reboot.
